To minimize noise and ensure optimal performance, it is recommended to follow a star-grounding scheme, keep analog and digital grounds separate, and use a solid ground plane. Additionally, keep the analog input traces short and away from digital traces, and use a low-ESR capacitor for decoupling.
To optimize the ADC's performance, consider the following: choose the correct gain setting, adjust the sampling rate to match the signal bandwidth, use the correct input range, and implement a suitable anti-aliasing filter. Additionally, consider using the ADC's built-in features such as the programmable gain amplifier and the digital filter.
The recommended power-up sequence is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and finally the clock signal. This ensures that the ADC is properly initialized and configured before starting conversions.
To handle the ADS804E's latency and pipelining, consider the following: understand the ADC's conversion cycle and latency, use the ADC's built-in FIFO to buffer data, and implement a suitable data acquisition strategy such as double buffering or ping-pong buffering.
When selecting an external reference voltage for the ADS804E, consider the following: choose a reference voltage that is stable and low-noise, ensure the reference voltage is within the ADC's specified range, and consider using a voltage reference with a low temperature coefficient to minimize drift.
